We never had issues with it slipping or jumping or breaking or ever coming off. We just find it very hard to write fast, accurate and repeatable autonomous modes with so much slack in our chain. It gives semi un repeatable results in our vision code when only the front 2 wheels move while the back 4 don't having to make up the distance in chain slack. It would have been much better to just run tensionors from the start.
